I have 2.5s and a REL Strata III subwoofer in an 11 x 13.5 room. I am running the REL off my amp and the speakers full range. I love it and would only consider ever changing speakers if amp changes made it necessary. I would only change the REL by ungrading to one of their larger models. It's a phenomenal pc of music making equipment. Actually, same thing for the ProAcs. I may be prejudiced but I think the 2.5 is a classic that we will be loving 10 yrs from now. I've had them over 5 yrs and still sit and admire 'em!
